SPECIFICATION forming part of LettersPatent No. 402,548, dated April 30,1889.

Application filed March 28, 1388. Serial No. 268,217. (ModeL)Improvements in Spring-Motors; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, refer- I once being had to the accompanying drawings, and toletters of reference marked thereon, which form a part of thisspecification.

The object of this invention is to obtain i11- creased power by acombination of a series of springs with suitable mechanisms at a re-'duced cost of construction, and is an improvement upon the mechanismheretofore described in an applicationfor Letters Patent made by me andfiled August 17, 1887.

The invention consists in the arrangements and combinations of parts,substantially as will be hereinafter set forth, and finally embodied inthe clauses of the claim.

Referring to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several figures,Figure 1 is a side elevation of a portion of the improved motor, thebalance-wheel, with its gear-connections, being removed. Fig. 1 is aside elevation of the improved motor complete. Fig. 2 is a sideelevation of a portion of the balance-wheel with its gear-connections.Fig. 3 is an elevation of one pair of the motorsprings. Fig. 4 is an endview of Fig. 3. Fig. 5 is an elevation of an auxiliary wheel with itsgear-connection. Fig. 6 is a top plan view of the motor frame andgearing, the springs being omitted. V

In said drawings, D indicates the frame or bed,of a machine.

B is the main or driving shaft, having pinion 25, into which meshesgear-wheel h h, h, h h, h and h are a series of gearwheels onspring-carrying shafts n, and each meshing into the one adjoining. Thusit meshes into h, h into 71 ,71, into h, and h into h and h into h. Bythis arrangement the power of the gear-wheels h h 71, 704 72. is alltransmitted to and concentrated in gear-wheel 7L2, which alone transmitsthe concentrated power to the main driving-shaft, the power of 71 beingtransmitted to h, which transfers it, together with its own power, to 71while 7L5 transfers its power to 7L which transfe'rs it,

together with its own power, to 71 which, in

its turn, transfers this concentrated power of h and If, which it hasreceived, as well as its own power, to 71 a is a gear-wheel on the rearof a drivingshaft, B, and meshing into pinion b on shaft 0, on whichshaft is gear-wheel (Z, which meshes into pinion e on fly-wheel shaft f.On the outside of the frame and, on driving-shaft B is a gear-wheehg.(Shown in Fig. 2.) This gearwheel meshes into a pinion, 2', onbalancewheel shaft k, carrying balance-wheel m. This balance-wheel shaftis supported at its outer end in proper journal bearings in frame a.

On the rear of the frame D is an auxiliary frame, 0, Fig. 5, in which isjournaled a shaft, 19, carrying gear-wheelq, imparting its motion andpower to pinion r on the rear of drivingshaft B,

. On shaft f is a fiy-wheel, s, and against its outer periphery isbrought to bear the brake it. This brake consists of a metallic shoe orbrake, Lt, adapted to bear upon the surface of the fiy-wheel s, and issupported by a lever, 42, having its opposite end forked so as topartially enfold the hollow rod 1, which carries the governor 2. Thislever 'v is pivoted to an arched support, 10, secured to frame D, asseen in Fig. 1. Opposite to the brake u and arranged to bear upon theopposite side of the fly-wheel s is a shoe, 8,Fig. 1. This shoe isattached to a thumb-screw, 1,.working in a threadedsocket in cross-bar5, secured to the frame D.

On each of the spring-shafts 'n are secured double springs 6 6,separated by a loose partition, 7, one end of each of said springs beingsecured to the frame D, as seen at 8, Figs. 1, 3, and at. These springswhen wound up are prevented from-unwinding by the common and well knownmeans of the pawl and ratohetwheel.

In my improved motor, the gear-wheelsbeing loose on their respectivespring-carrying shafts, the same do not turn when the springs are woundup,and thus I am enabled to wind up any of the springs without stoppingthe machine or in any way interfering with the running of the machine.This is accomplished by securing the ratchet to the springcarrying shaftand attaching the pawl with its holding-spring to the gear-wheel, asshown in Fig. 4. This allows the gear-wheel to turn with thespring-bearing shaft when it is unwinding or transmitting power, but notto revolve with the shaft when the springs are wound up. The springs arewound up in the usual manner by a crank placed on the end of the shaft.By this arrangement of a loose gear-wheel I am enabled to wind up any ofthe springs without in any manner interfering with the working of theothers;

It is manifest that the frame can be extended and any number ofspring-bearing shafts could be employed, thereby greatly increasing thepower of the machine.

011 the shaft 13 is placed gear-wheel q, as seen in Fig. 5, and is looseon the shaft. This shaft also carries and has secured to it one end of aspring, 9, the other end of the spring being secured to a lug, 10, onframe 0. This gear-wheel works in the same manner on its shaft asgear-wheels 71, &c., already described. The said gear-wheel q mesheswith a pinion, 7', on the rear of the main shaft, and its revolutionaids and assists the various motive springs while unwinding or while oneof the series is being wound up while themachine is in motion. Whenwinding up the machine the shoe is screwed up against the fly-wheel, soas to prevent any of the wheels from revolvin g when one or more of theseries of motive springs may be wound up according to the amount ofpower required.

To start the machine, the shoe 3 is gradually released from contact withthe fiy-wheel by means of the thumbscrew, the action of the spring (orsprings) that are wound up causes all the wheels to revolve, and thedegree of speed is regulated by the regulator, the brake being caused toimpinge upon the fly-wheel to a greater or less degree, according as thelever o is raised or lowered by the regulator, as will be understood.The frame D can be secured to feet, if desired.

Having thus described theinvention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a spring-motor, the combination, with the main frame and drivingshaft of the machine, of a supplemental frame, 0, shaft 1), jo'urnaledin said frame 0, spring 9, auxiliary gear-wheel q, independent of butconnected with the spring driving mechanism, and pinion 7', connectingsaid auxiliary gear-wheel with the driving-shaft of the machine,substantially as shown, and for the purposes set forth.

2. In a spring-motor, an auxiliary spring driving mechanism consistingof a supplemental frame, 0, shaft 1), journaled in said frame 0, spring9, auxiliary gear-wheel q, independent of but connected with the springdriving mechanism, and pinion r, connecting said auxiliary gear-wheel qwith the main drivingshaft of the machine, in combination with the mainspring driving mechanism consisting of a series of spring-bearingshafts, n, gear-wheel 7L2, revolving on one of said shafts n and meshinginto pinion t on main shaft, a series of gear-wheels revolving onsimilar shafts, n, and arranged to transmit their united power togear-wheel 71 and pawl-and-ratchet devices connecting saidgear-wheelswith their respective shafts, all as shown and described, andfor the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this3d day of March, 1888.
